Abstract
A computer-implemented device and method for identifying hardware Trojans and defects based on light emissions from Integrated Circuits (ICs) is provided. A measured emissions map is received based on light emissions captured from a sacrificial test IC. The sacrificial test IC is a partially manufactured IC fabricated to include a set of frontend layers of an IC architecture but not a set of backend layers of the IC architecture. The sacrificial test IC also includes a sacrificial layer for powering devices in the partially manufactured IC without the set of backend layers. An expected emissions map is derived from the sacrificial test IC and the measured emissions map is compared with the expected emissions map to identify deviations from the IC architecture in the frontend layers.
